At your minimal weight, and with the pretty decent skills you have, it sounds like if you would need a MUCH smaller board. It of course depends on what size sails you are using, but I have a hard time believing that you ever would need a bigger sail than a 6.0.

In you shoes I would start looking for a board no bigger than 95 liters. In this size there are still a few freeride oriented boards. You could probably manage really well with a even smaller board, like a freestyle wave (e.g. Kode) in the 85 liter range.

The Futura 111 isn't a bad choice considering that you are stepping from a Kode 122. Like PG mentions, it might be too close to the 122 in size though, so you might outgrow that board quite fast. Futura 101 is one alternative I'd consider.
